Just have a button on the Farming Menu (or second menu) that says Edit Options, which will bring it back up.
Update on this last test. The Rune number of secure does not save when I hit Save Setup, also when I add a location to the list after I've already generated 1 per recall spot, it does not use it before recalling.
Example. I have 16 spots saved, one tree at each spot. I then set up 2 more at Recall location #1. These two spots are set at the end of the list, and are not attempted until the 17th and 18th try, instead of 2nd and 3rd. Not sure if that makes sense.
Edit:
Pathfinding is still not working in Felucca. I set up rune 1 with 4 locations, in a row, about 4-5 tiles apart from each other heading north. I went from tree one, paused for a bit with the message "You can not reach that" then it ran to tree 3, farmed, then said "You can not reach that" for tree four, then ran back to tree one (at that point I'm assuming it would recall to rune 2, but since I did not set it up, it ran back to rune 1 location.) Attempted to farm, tree was empty and ran back to tree 3, rinse and repeat over and over.
Edit #2:
I set up 3 spots with 2 tree's at each, roughly 4-8 tiles away from the first tree (recall location). It goes through all 6 tree were farmed, going to test out 3 tree's at each recall location, see if that works.
Continuation of Edit 2:
Seems to be working great. So if somebody just sets up one rune to run around and farm, it does not like that mojo. However I did find a bug while doing this. If your recall location is blocked, your little bubba will just sit there and attempt to recall to that spot over and over and over keeping you stuck in a endless loop of not recalling. Needs to select the next recall spot in the book and move on.
Edit #3
I found out the issue with Pathfinding that was causing an issue for me not farming from the next tree. If you have to travel in a odd way, left right up left... it takes too long to get to the tree and he stops or does not farm. So you need a clear shot and quick route to get to your tree.
